The CodeyBot Review

The codeybot is a Makeblock product that was launched on kickstarter and is a wheeled robot that is targeted towards education and experimentation. It can be programmed using the mBlocky app downloadable from the Play store as well as the App Store. It can also be controlled using a limited set of voice commands as well as using the Phone’s accelerometer. The most interesting thing about this robot is the fact that it can balance on two wheels and can dance and play music.

As backer no1 on kickstarter, I got my hands on the bot and did an unboxing video here.

The codeybot is built intelligently and the guts are quite well placed. I would have liked to see the connector description somewhere but thats ok since I did a teardown of the turret and then the bot which I will cover in the next post.

The app seems a bit cluttered with all the functionally crammed into one screen but can work if you have an iPad or android tablet.

The mBlocky app is clean and works well out of the box

The fun begins when you have two of these and can convince a friend to play laser tag with you. You get an assortment of weapons and two codeybot paired together can be hours of fun together.

We will be sharing the details of the codeybot and turret teardown in the next post so please like and subscribe the video on youtube and if you have any suggestions of comments, feel free to put them the in the box below.
Thanks and happy hacking.

Seeedstudios Groove Pi+ Pre-Review Part 1

Introduction

SeeedStudios has their own system of prototyping hardward called Grove which uses four pin connectors to connect sensors, actuators and subsystems together to a central controller which can be arduino based or MSP430 based. Recently, they have introduced an interface to the Rapberry Pi called the grovepi+ which is a Raspberry Pi Hat with an Atmega328P which allows the RPi to take advantage of the grove widgets. I was one of the people who got their hands on one of the pre-review units in a Kit form and I decided to do a little something with it. In this article I will go through the basic kit and it’s contents and my first impressions since this is the first time I am using the Grove System. I had a few preconceptions and I will discuss my experience with the kit so far along with a project plan I have going. Lets go! Continue reading “Seeedstudios Groove Pi+ Pre-Review Part 1”

Single Board Computers- The Arduino YUN Review

SBC

Prelude

Hackers and hobbyists have used the arduino for a diverse number of projects and have made it a very popular. Its simple to use and easy to program. For people who have a slightly ‘more’ requirement, ARM based single boards came into the market. Initially the ARM boards were tougher to build and program and costlier to make. In order to fully exploit the power of a 32-bit processor, the Linux Kernel was ported to the fanless ARM systems making the Single Board Computers. The OS was stored on either an SD Card or an EEPROM. This new class of boards had the familiar OS system of a regular PC and the digital and analog outputs of the arduino but at a slightly higher cost. Additionally they had varying performance but they started to add something more- peripherals! Keyboard, then Ethernet, then Bluetooth and Wifi- the list goes on. In this article we discuss the Arduino YUN and what exactly it is. Continue reading “Single Board Computers- The Arduino YUN Review”

The Raspberry Pi Power Analysis featuring the Tektronix Scope

Introduction

I am waiting for my stuff to get delivered which are basically parts and parts. One of features of my design is that the raspberry pi center piece is portable, ie it can be moved from one location of the house to the other. For this I needed to add a battery backup which was shown in my previous posts. In my recent experiments, I found that the Raspberry Pi was rebooting unexpectedly. It turns out that one of the connectors was defective. Still this left me with the question that if I am using a battery, how long will my system stay afloat without power? Hence I setup a little experiment to measure the power consumed by the Raspberry Pi and the results were quite unexpected.

CapSense MBR3 Evaluation Kit – Review

CapSense MBR3 with Arduino Nano

Introduction

A lot of projects and products involve a user interface which is buttons and switches and knobs. The cost of industry grade panel push buttons is really high and it gets worse as the buttons become environment proof. With that said, Capacitive Touch sensing has come in to replace mechanical buttons and the Cypress CapSense MBR3 does exactly that. The solution is a single chip auto calibration system which does most things for you. Most Capacitive Touch sensing solutions offered need a lot of technical expertise but Cypress claims that their solution is just easier to use. I will be reviewing the developer side of the solution as opposed to the kit itself. Continue reading “CapSense MBR3 Evaluation Kit – Review”

Tektronix TBS1202B-EDU Oscilloscope for Education

Tektronix TBS1202B-EDU

1. Overview

The Tektronix – TBS1XXXB-EDU series of Oscilloscope have been targeted towards the educational sector. The logo on the front panel that says “Enabling teaching” is proof of that. The traditional approach has been to carry a paper manual where the students will find the detailed instructions to the experiment to be performed. The experiment is setup on a breadboard or on a kit or sorts. Continue reading “Tektronix TBS1202B-EDU Oscilloscope for Education”
